Quotes from Earthlings

I am aware that there are many who wince at a distinction between property and persons — who hold both sacrosanct. My views are not so rigid. A life is sacred. Property is intended to serve life, and no matter how much we surround it with rights and respect, it has no personal being. It is part of the earth man walks on; it is not man.

— Martin Luther King, Jr., The Trumpet of Conscience (1967)

Can we construct adversarial electricity portfolios made of new zero-carbon resources that undermine the profitability of specific existing fossil plants? Some version of this is already happening, but it’s incidental rather than targeted. The economics of existing coal and nuclear plants are being eroded by flat electricity demand in combination with cheap gas, wind, and solar. Economical storage and dispatchable demand aren’t far behind. But how much faster would the energy transition be if we actively optimized new energy resources to undermine the economics of existing fossil generation?

In my last post, I recounted some of the indications that have surfaced over the last decade that US coal reserves might not be as large as we think. The work done by the USGS assessing our reserves, and more recently comments from the coal industry themselves cast doubt on the common refrain that the US is “the Saudi Arabia of coal” and the idea that we have a couple of centuries worth of the fuel just laying around, waiting to be burned. As it turns out, the US isn’t alone in having potentially unreliable reserve numbers. Over the decades, many other major coal producing nations have also dramatically revised their reserve estimates.

Internationally the main reserve compilations are done by the UN’s World Energy Council (WEC) and to some degree also the German equivalent of the USGS, known as the BGR. Virtually all global (publicly viewable) statistics on fossil fuel reserves are traceable back to one of those two agencies. For instance, the coal reserve numbers in the International Energy Agency’s (IEA’s) 2011 World Energy Outlook came from the BGR; the numbers in BP’s most recent Statistical Review of Energy came from the WEC.

Of course, both the WEC and the BGR are largely dependent on numbers reported by national agencies (like the USGS, the EIA and the SEC in the case of the US), who compile data directly from state and regional geologic survey and mining agencies, fossil fuel consumers, producers, and the markets that they make up.

Looking back through the years at internationally reported coal reserve numbers, it’s surprisingly common to see big discontinuous revisions. Below are a few examples from the WEC Resource Surveys going back to 1950, including some of the world’s largest supposed coal reserve holders. In all cases, the magnitude of the large reserve revisions is much greater than annual coal production can explain.

From the all-too-rare genre of mathematical-political satire: Using Metadata to find Paul Revere. Highlighting for the uninitiated just how much actual information is really contained in even a wee sliver of the so-called metadata we smear all over the digital universe in our wake. Applied to the Founding Fathers.

A long format talk by Hans Rosling at the Open Knowledge Festival, on the importance of not just liberating public data, but also using it to weave engaging stories for the public about the facts of the world as we know it exists today. It does no good to allow students to debate why women in the Muslim world have more children than elsewhere, because it isn’t true. Sweden still sends foreign aid to China, even though China just bought Volvo. People think that 30% of our power comes from wind and solar, because wind and solar grew 30% last year. Why don’t more activists demand good data? Why don’t they use it to build fact-based cases for their causes, instead of seeking out only the data that confirms their pre-existing ideologies?

Lawrence Berkeley National Labs has put out a report on the state of the wind energy industry, as of the end of 2011. I didn’t realize that the price trend had been so uneven over the last decade. The cost of wind power was dropping in the early 2000s, and then rebounded, peaking in 2008/2009 due to shortages in the turbine supply chain, before again dropping in the last year or two. I started looking into these prices because I’m reading a Renewable Energy Policy by Paul Komor (2004) and the prices he quotes ($40-$50/MWh) seem low, relative to the numbers from Xcel’s ERP and the recent bids I saw in Michigan (more like $60/MWh), but the book was written right at the wind price bottom. I’m also shocked at how wide the spread in costs is, even in just the last couple of years. California is paying $100/MWh for huge projects, and in the wind belt some projects are coming in more like $25/MWh. That’s got to be largely policy driven, and it indicates we’ve got a woefully inefficient market for wind.

The human timescale isn’t appropriate for climate change. We can’t see it minute to minute. Day to day. Year to year. Like watching an analog clock, you never see the hands move, and yet time passes. We need more time lapse eyes.

The National Snow and Ice Data Center (NSIDC) in Boulder automatically generates this plot of arctic sea ice extent (and many others) every day:

OpenPaths is a mobile application that allows you to log your location in a way that minimally impacts your phone’s battery life, and keeps that information secure (supposedly out of reach of law enforcement w/ zero knowledge encryption) while still allowing you to do interesting things with it, via an OAuth API.
